Plumbing problems

Boy, did we wish my brother, David was here yesterday. We had plumbing problems and Dan was trying to unclog as much as he could, but there was more than he could get to. David!!!!Help!!!! I haven't washed laundry for five days because it keeps backing up and leaking all over the floor. What a mess!! At least we have a clean floor now! It should get fixed today or tomorrow, hopefully....! At least my wonderful husband is doing as much as he can!
